(CNN)She is just 24, but Claressa Shields isn’t afraid to describe herself as the “greatest woman of all time.”
Bold perhaps, but there’s plenty of supporting evidence behind the braggadocio of Shields, whose nickname is “T-Rex.”In April, she became the world’s undisputed middleweight champion after defeating Germany’s Christina Hammer in Atlantic City. Shields is only the second woman after Cecilia Brækhus to hold the IBF, WBA, WBC, and WBO belts in a single weight category, and just the sixth person ever. None, however, did it as quickly as Shields, who reached the pinnacle of her sport in just nine fights. “There’s not a woman in this world that can beat me if we put on a pair of gloves and we fight. I’ve accomplished so much,” Shields, who also won gold at the 2012 and 2016 Olympic Games, tells CNN.

In defeating Hammer, she conquered her toughest opponent to date, an undefeated fighter with 11 knockouts to her name.

You just continue to be great and you make your own life.”I grew up on North Saginaw, the north side of Flint, which is considered the worst part and I was able to make it; I was able to make it by just making smart decisions from a very young age.”I tell all kids and the girls growing up that you control your own life, you control your destiny — not where you’re born, not who your parents are.”JUST WATCHEDFemale Olympic boxer punches for goldReplayMore Videos …MUST WATCH

With women’s tennis and men’s tennis it’s kind of equal, so I want to get back into the same place.”Shields gets a jab through Hammer’s guard at their recent fight Diet of a championShields admits that doubts arise ahead of big fights, but has faith her rigorous training regime will come good in the end. “Whatever is the worst thing that can happen, I think about it and I just do everything in my power to not make it happen,” says Shields.”I know that the doubt is there, but the doubt gets erased in training camp … it gets erased when I know I’m busting my butt in camp.”A second Olympic gold came for Shields at Rio in 2016JUST WATCHEDAnthony Joshua on boxing, Brexit and NigeriaReplayMore Videos …MUST WATCH
